Seeing through the shades of situated affectivity. Sunglasses as a socio-affective artifact

Debates on situated affectivity have mainly focused on tools that exert some positive influence on affective experience. Far less attention has been paid to artifacts that interact with the expression of affect, or to those that exert some negative influence. To shed light on that shadowy corner of our affective social lives, I describe the workings of an atypical socio-affective artifact, namely, sunglasses. Drawing on insights from psychology and other social sciences, I construe sunglasses as a social shield that helps us block spontaneous emotional expressions, as well as affecting other social processes that heavily depend on the eye region: gaze direction detection, identity recognition, and the sense of intimacy afforded by eye contact.
